A Reverse Cycle system use refrigerant gas to produce either warm or cool air. A system generally has two major components, the indoor unit for the home or office, and an outdoor unit, commonly called the compressor. The compressor pumps refrigerant through pipes to the indoor unit, where air is blown over the pipes then out into the room. This can provide cool air, like a traditional air conditioner, or warm air if the cycle (gas flow) is reversed.

Reverse Cycle systems can come in a variety of forms, from split-systems, to multi-head, to ducted. They also come in a range of power outputs. To find out what is most suited to your needs, contact us here.

An add-on cooling system is an attachment to a gas ducted heating system that provides refrigerated cooling to the existing duct network. This allows for heating and cooling through only one system and one controller, utilizing the efficiencies of gas heating and air conditioned cooling. Generally it is not something that can be fitted to an existing gas heating system, however, as the gas heater needs to be designed to allow greater airflow than is normally required.

For more information please contact our specialists here.

Zone control is a very good way to warm or cool a whole house, or just parts of it, with one central ducted system. With zone control your family can be comfortable in different rooms with their own personal settings. Our specialists can provide you with information on zone control and other features here..

We service Melbourne-Wide and Geelong Areas. Our HVAC consultants and installers are distributed all over Melbourne to satisfy all residents’ demands.

A multi-head is a split system with one large outdoor unit (compressor) and many indoor units connected to it. Some multi-head compressors can handle up to 6 or 7 indoor units (heads), depending on the power output of the compressor and the power consumption of the heads.

A multi-head system is a convenient way to provide heating or cooling to 2 or 3 (or even 6 or 7) rooms with only one compressor, providing individual comfort without the need for a full ducted and zoned system. It is also a fantastic option where ducts cannot be run through the ceiling, like an apartment; or under the floor, as with a concrete slab foundation.

Depending of the type of work, the installation time can vary.

• Example 1: Simple replacement/changeover = Half – 1 day
• Example 2: New installation with ducting = 1 – 2 days

Rest assures our project coordinator will inform you the approx. timeframe before we schedule your job for installation.

Yes, we do! And not only that, all installation will ONLY be performed by our own internal installation team to guarantee the quality of our work.
All installation performed by ComfyHome Heating & Cooling comes with 6 Years Workmanship Warranty.

A refrigerated cooling system uses the air already in the room, cools it and blows it around the room. For best effect and efficiency, the area it is cooling should be closed off from outside. It is a great option on hot days as the heat of the air outside is kept outside.

An evaporative system takes the warm outside air, filters it and blows it over water-soaked pads, cooling the air, then out into the home or office. This provides fresh, clean, cool air to make you comfortable. For best effect and efficiency the room should have an open door or window to allow the flow of fresh air.

Due to the range of cooling options and system strengths it is best to ask our specialists for further details here.

No – not unless you are a licensed plumber, electrician or both, depending on the system you have. The manufacturer warranties for all HVAC systems are only issued with compliance certificates from Licensed personnel.

The principle of an Evaporative Cooling system is no rocket science!

Evaporative Cooler works by drawing warm outdoor air, where it passes through “water-saturated cooling pad” and convert into cool air. Then the cooled air is distributed to each room through the ducting system.

Unlike some of our competitors selling a particular brand with a fixed dealership.
ComfyHome offers a broad range of evaporative cooling brands that are proven, reputable & quality guaranteed such as below;

Yes, there are many different terms for Evaporative Cooler includes Evaporative Air Conditioning, Evaporative Air Conditioner, Evaporative Cooling, Evap Cooling, Evap Cooler.

In some states in Australia, they even call it a “Swamp Box” or “Swamp Cooler”!

An Evaporative Cooler can potentially lower the ambient temperature by up to 7-10 °C. But it depends on the air temperature, water temperature in the evaporative cooler and most importantly the humidity level in your room that may affect the efficiency of an evaporative cooler.

For optimal performance, an evaporative cooler works best in dry climates!

Evaporative cooler relies on constantly supplying 100% fresh & clean air into your home, the air does not recirculate through your home.

Filtered & humidified air also helps individuals who suffer from respiratory difficulties and allergies problems.

Evaporative Cooling relies on the natural method of replacing the air in the home to provide cooling. A general rule of thumb, each room with an outlet should have a window open approx. 100mm for air relief. Or the other simple equation is to aim to creating opening area twice the area of the outlets opening.

Gas Ducted Heating is powered by natural gas or LPG, it works by drawing air from inside your home through a fan and heat up through the “heat exchange” which then the warm air distributes through the ducting system into each room.

The return air grill is installed to recirculate warm air back to the heater where the process repeated.

Add-On Cooling is a cooling unit that can be added to your existing or new Ducted Heating System.

However, in most cases, if you already have an existing Ducted Heating System, there’s a good chance that your heating unit and ducting may not be cooling-compatible.

The best practice is to confirm with our Add-On Cooling professional at ComfyHome to ensure your existing ducting size and heating unit has sufficient airflow output for Add-On Cooling before purchasing.

An average lifespan of a Ducted Gas Heating System with regular routine service should probably last 10-20 years.

If you have never had your heater serviced, we strongly suggest that you should book in a service for your ducted heating system immediately before using.

Ducted Refrigerated Air Conditioning works by creating cool air from an outdoor condenser, connected through pair coils and attached to an indoor fan coil unit (in roof cavity).

The cool air is then distributed through a ducting network via a group of outlets into each room.

Generally, it should take around 1-2 days for new installation of a Ducted Air Conditioning System with 5-10 outlets.

The actual timeframe may vary depends on some of the following factors;

• How many outlets / vents are required in the installation?
• Where will the outdoor condenser and indoor unit be installed?
• Will zoning be added to the Ducted Air Conditioning System?

We will advise you an estimate of timeframe of installation prior to commence of work.

An example of a standard 12.5kW Ducted Reverse-Cycle Air Conditioner fully supply & install to 5 outlets will cost around $7000.00 – $9000.00 in Melbourne.

The actual cost of Ducted air conditioning installation can vary depending on plenty of factors such as the brand, size of unit, complexity of installation etc…

You may find out more information in the Ducted Refrigerated Page. Or check out the some of the latest Ducted air conditioning prices in our Promotion Page.

Unlike our competitors in Melbourne with a fixed dealership on a particular brand.

ComfyHome offers a wide range of Ducted Air Conditioning brands that are proven, reputable & quality guaranteed as per below listed;

• Daikin
• Mitsubishi
• Fujitsu
• ActronAir
• Haier
• Gree
• Rinnai

Rather than one brand sales approach, we focus in specialised personal approach that fit your home and your needs.

To work out the estimated running cost / per hour of Ducted Air Conditioning, use one of the following equations;

• 1.Power Input (kW) x kilowatt hour cost $ (kWh) = Running Cost / hour
• 2.Cooling capacity (kW) / E.E.R. x kilowatt hour cost $ (kWh) = Running Cost / hour

Power Input and E.E.R. (Energy Efficient Ratio) should be listed in the Energy Star Label or specifications of the system, while kilowatt hour cost can be found on your last electricity bill.

Scenario: If your Ducted Air Conditioning System has 16kW cooling capacity, and the E.E.R. is 3.13, the power input will be (16 / 3.13 = 5.11 kW). If your local electricity cost kWh is 40 cents, your Ducted Air Conditioning System may cost around (5.11 x 0.4 = $ 2.04) per hour to run.

Please note that this is an estimation of running cost for reference ONLY, actual running cost may vary depending on your local energy provider, zoning, temperature setting, climate environment and the capacity of your system.

The formula to find out the approx. size of Ducted Air Conditioning for your home is:

Day Time Cooling Area(m²) x 150 watts = Size Capacity Required (kW)
For a day time cooling area of 100 m², the ideal size of your Ducted Air Conditioning will be (100m² x 0.15= 15 kW).

Please note that the formula is for reference ONLY, the actual size of Ducted Air Conditioning required can also be affected by other variables like the ceiling height, roof insulation, the Rating of duct insulation, number of occupants and residents’ location etc…
For an accurate assessment of the required Ducted Air Conditioning size, we recommend you Contact Us for a detailed analysis.

Yes, there are many different terms for Ducted Refrigerated Air Conditioning such as Ducted Reverse-Cycle, Ducted Air Conditioning, Ducted Air Con, Ducted Heating & Cooling etc… They ALL means the same thing.

In short, the key consideration will be your heating demand.
Gas Ducted Heating is no doubt the most efficient whole house heating system as it runs on gas than electricity, the max. heating capacity for Ducted Heater can reach up to 35kW compare to 18kW (Ducted Air Conditioning).

Therefore, Ducted Reverse Cycle Air Conditioning is ideal if you don’t have a huge heating demand and it can be slightly cheaper to supply & install.

Sizing the cooling capacity required for your home can be tricky. A general rule is to multiply the cooling area (m²) by 150watts. As an example: The calculation of a house with 100m² cooling area will be (100m² x 150watts = 15kW).

This only give you a rough idea as there are many variables will affect the results such as ceiling height, roof and room insulation, star rating of ductwork etc…

The most accurate way to find out the size of Add-On Cooling is by scheduling a home consultation with ComfyHome, we will measure up your home to help you find the perfect sized unit you need. Call us on 1300 266 394.
